10 Claims.

This invention relates to vending machines, and has particular reference to a machine especially designed iorvending articles such as peanuts, candy balls, chewing gum balls andthe like.

The general object of the invention is to provide a machine for vending articles of the character mentioned, which machine is of simple, strong and durable-construction and of comparatively low production cost, and'which is thoroughly reliable and efiicient'in operation.

More particularly, the invention has in view to provide, in a machine for vending articles of the character mentioned, novel and simplified means to prevent operationof the machine except by the deposit of a proper coin or check in the machine; a novel combination and assembly of a pair of cooperating coin or check controlled ar-" ticle delivery members; a novel delivery spout mounting and a novel mounting for the spout cover; a novel arrangement of spring meansfor returning the movable elements of the machine to their normal positions following vending'or' dispensing actuation of said elements, and, in general, a compact, simplified assembly of all of the operating parts of the machine and a sturdy construction of such parts.

With the foregoing and various other objects in view which will become more fully apparent as the nature of the invention is better understood, the same consists in thenovel features of construction and in the novel combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the different views:

Fig. 1 isa front elevation of a vending machine constructed in accordance with the invention.

Fig. 2 is a top plan view of the machine with the article holder removed.

Fig. 3 is a bottom plan view of the machine with the bottom cover plate removed.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is a section on the line 5'5 of Fig. 2.

Fig. 6 is a top plan view of the lower of the two rotatable and cooperating dispensing members.

Fig. '7 is a top plan View of the upper of the two rotatable dispensing members; and

Fig. 8 is a detail sectional view on the line 8-8 of Fig. 4.

Referring to the drawings in detail, it will'be observed that the machine is inclusive of a hollow base A, that the top of said base is closed by a wall ID, that a hollow member B closed at its top by a wall H and open at its bottom, rests on the top wall 10 of the base, and that a container C for the articles to be Vended is supported at its open bottom on the top wall I l of the member B through an interposed gasket I2 and at its open top is closed by a removable cap or cover l3.

Formed through the top wall ill of the base A is an article delivery opening l4, and underlying this opening is the inner end portion of a delivery spout [5 which extends downwardly and outwardly to the exterior of the base A through an opening IS in the side wall thereof.

Formed centrally through the top wall It or the base A is an opening H, and extending downwardly through this opening is a threaded rod l8 which is provided, above the wall Ill, with an enlargement I!) which engages the upper side of said wall and thereby limits downward movement of said rod.

The inner end portions of the side walls of the L spout l5 are formed with flat top edges to engage the under face of the top wall ll! of the base A to either side of the delivery opening M in said top wall, while extending inwardly from the inner end of said spout i5 is tongue 20 which lies against the under side of the top wall It and which has the rod 18 extending downwardly therethrough. A washer 2! on the rod 18 engages the under face of the tongue 25, and threaded on said rod against said washer is a nut 22 which serves to clamp the spout 15 in its operative position against the under side of the top wall ll! of the base A as shown in Fig. 5 of the drawings.

Recesses are formed in the side walls of the spout 'l 5 and open through the upper edges thereof, and in these recesses are seated trunnions 23 which project laterally from the sides of a spout cover 24, whereby the spout cover is mounted to be raised to permit the vended articles to slide out of the trough l5, and to drop by gravity to a normal position, as shown in Fig. 5 in which a downward projection 25 near its free or outer end closes the outer end of the spout.

The rod 1 8 extends upwardly from the enlargement I9 through a central opening in the top wall ll of the hollow member B and, above said wall H, has threaded thereon a nut 26 which is drawn tightly against said wall I 1 thereby to clamp the hollow member B securely against the top wall H] of the base A. Another rod 21 is threaded at its lower end into the nut 26 and at its upper end extends through a yoke 28 depending from a plate 29 and has threaded thereon 'a nut 30 whereby the plate 29 is clamped against the top of the container C and the latter is clamped against the hollow member B. The cap l3 serves to close an opening in the plate 29 through which the container C may be filled and through which access may be had to the nut 36, and said cover normally is fastened in position closing the top of the container by a padlock 3|.

It is, of course, necessary to provide means to prevent rotation of the container C relative to the hollow member B and rotation of the latter member relative to the base A, as otherwise it would be possible by relative rotation of these parts to effect their disassembly. This may be accomplished in any desired manner, but a practical means for accomplishing the purpose resides, as shown, in forming the member B of octagonal or other polygonal shape, in providing lips or flanges 32 on the base A to engage one or more of the flat sides of the memberB, and in forming the lower, open end of the container C of octagonal or other polygonal shape and providing an upstanding flange 33 at the top of the member B to embrace the lower end of the container.

As best illustrated in Figs. 2, 4 and 5 of the drawings, the top wall ll of the hollow member B is provided with an opening 34 through which articles such as peanuts, candy or chewing gum balls or the like, contained within the container C, may gravitate into said hollow member, and in order to assist gravity in causing the articles to gravitate through said opening, the said top wall H is inclined downwardly towards said opening.

The opening 34 is of somewhat elongated, arcuate shape and is disposed diametrically opposite the discharge opening id in the top wall In of the base A, while arranged within the hollow member B are upper and lower cooperating, relatively rotatable, coin-controlled, disk-like elements 35 and 35, respectively, which are operable to convey the articles gravitating through the opening 34, to the opening I4.

The upper disk-like element 35 is journaled on the rod l8 and is supported on the upper face of the enlargement E9 of said rod with its lower edge suitably spaced above the top of the lower disk-like element 36 which is journaled on the enlargement l9. free to rotate without tendency to impart rotation to the other disk-like element, except as hereinafter explained.

The lower disk-like element 36 has formed therethrough a relatively wide, arcuate slot 31 of considerable circumferential extent as illustrated in Fig. 6 of the drawings, while opening through the top of the upper disk-like element 35 is a well 38 which is open at its bottom and the lower portion of which is defined by flange-like walls 39 which depend from said upper disk-like element 3:: through the slot 31 in the lower disklike element 36 and terminate at their bottoms slightly above the top wall HJ of the base A.

Formed in the upper disk-like element 35 and opening through the edge and the bottom thereof is a coin slot 33, while formed through the lower disk-like element 36 and opening through the edge thereof in a coin slot 4|. In addition, the side wall of the hollow member B is provided with a coin chute or slot 43 and also with a circumferential slot 44 through which extends an operating handle 45 which projects outwardly from the lower disk-like element 36.

The lower disk-like element 36 is rotatable through a fixed angle which may be predeter- Thus, each disk-like element is mined in any suitable manner, as, for example by the length of the slot 44 the ends of which constitute abutment-s engageable by the handle 45, or by providing any other suitable spaced stops engageable by the handle 45 or by any other suitable abutment carried by said lower disklilze element, and. the arrangement in this respect is such that when said lower disk-like element 36' is at its limit of movement in one direction, 1. e., its normal, retracted position, its coin slot 4! is alined with the coin chute 43, the wall defining the forward end of its slot 31 is engaged with the forward depending flange wall 39 of the upper disk-like element 35, and the well 38 and the coin slot 40 of the latter element are alined, respectively, with the opening 34 in the top wall I I of the hollow member B and the coin chute 43.

Yieldable means are provided to tend constantly to urge the disk-like element 36, and thereby the disk-like element 35, to their normal, retracted positions mentioned, and in the present instance this yieldable means comprises a spring 46 coiled about the rod l8 and having one end suitably anchored, and its other end extended upwardly through an arcuate slot 4! in the top wall l-O of the base and suitably engaged with the disk-like element 36 as indicated at 48'.

The forward end of the slot 41 is alined with the coin chute 4.3 and is of only slightly narrower width than the diameter of the particular coin or check through the instrumentality of which the machine is rendered operative. On the other hand, the length. of the chute or slot 43 in cross section is such as to prevent the insertion therein of a coin or check of greater diameter through the particular coin or check through instrumentality of which the machine is rendered operative. Thus assuming that the machine is to be rendered operative by the insertion of a penny in the chute or slot 43, it is apparent that a coin or check of greater diameter than a penny cannot be inserted in said chute, and that if a coin or check of lesser diameter than a penny is inserted in said chute it will pass through the alined slots 40 and 41 in the disk-like elements 35 and 36 respectively and drop through the forward end of the slot 41 into the base of the machine. If, however, a penny is deposited in the chute 43 it will roll down said chute and will enter the alined slots 40 and M, but will not gravitate through the slot 4'! due to the penny being of greater diameter than the width of said slot 41. Consequently, the two disklike elements 35, 36 will be interlocked by the penny and rotation of the lower disk-like element 36 will result in rotation of the upper disklike element 35 therewith.

In view of the, foregoing the operation of the machine will be apparent: The spring 46 holds the disk-like element 36 normally retracted with its coin slot 4| alined with the coin chute 43,, and since the wall defining the front end of the slot 3.! in said element 36 engages the front wall 39 of the well 38 of the disk-like element 35 when the said disk-like element 36 is retracted, the disk-like element 35' is held in a retracted position in which its coin slot 46 is alined with.

the coin chute 43 and the coin slot 4! of the element 36', and in which its well 38 is alined with the opening 34 in the top wall H of the hollow member B. Thus, normally, the well 38 is filled due to articles gravitating into the same from.

the .container C. Now, unless a proper coin or check is inserted in the chute 43 to interlock the disk-like elements 35, 36, rotation of the disk-- like element 36 by its handle willsimply result in idle rotation of said disk and lack of rotation of the disk 35, because the slot 31 in the disk-like element 35 is of such length as to permit full rotation of said disk-like element 35 to its forwardmost position without contact ofthe wall defining the rear end of its slot 31 with the rear wall 39 of the well 38; On the other hand, if a proper coin or check is inserted'in the chute 43 suoh'coin by reason of being-re tained in the slots 48, 4! of the disk-like elements 35, 36 will interlock, said disk-like-elements for unitary rotation, and thus, if the disk-like element 36 then is rotated to its forwardmostposition the disk-like element 35 will be correspondingly rotated with the result that the closed portion of the disk-like element 35 rearwardly of the well 38 will move beneath the opening 34 and will, in effect, close said opening, and the well 38 will become alined with the opening 14 with consequent gravitation of the contents of said well through the open bottom thereof and through the opening l4 into the spout l5. Then, upon release of the handle 45, the spring 46 will function to retract the disk-like elements 35, 36 to their normal positions in which the well 33 again will become filled in readiness for the next operation of the machine.

By reference to Fig. 3 of the drawings it will be observed that the slot 41 is widened at its rear end as at 49, for the free passage of a coin therethrough and that the walls defining the sides of said slot are of saw tooth or ratchet form whereby, once a proper coin is inserted in the chute 43 and forward rotation of the disk-like elements 35, 33 is initiated, it is impossible for said elements to be retracted until their forward or article dispensing rotation has been completed because of the coin cooperating as a dog with the ratchet teeth until the coin is advanced into alinement with the widened portion 49 of said slot 41. Consequently, it is not possible to inany way refill the well 38 during any one cycle of operation of.

the machine.

In order to provide for varying the effective capacity of the well 38 there is employed aplate.

53 which is disposed in a recess in the top of the disk-like element 35 and which has a fiange 5| depending into the well 33 and constituting the efiective rear wall of said well. The plate 50 is slotted as at 52 and a fastening screw 53 extends through this slot into the element 35. Thus, the plate may be adjusted to dispose its depending flange closer to or farther away from the front wall of the well 38 thereby to vary the effective capacity of the well, and, of course, by means of the screw 53 the plate may be fastened in any desired adjusted position.

Preferably, but not necessarily, the upper disklike element 35 is provided with a wire arm or the like 54 which extends upwardly through an arcuate slot 55 in the top wall I l of the member B into the container C so as to move with said disk-like element 35 and thus agitate the contents of the container in the vicinity of the opening 34 each time the machine is operated, thus to loosen the articles in the container in the event they may tend to jam and to assure filling of the well 38.

Following delivery of articles into the spout l5 the cover 24 may be lifted at will to permit the articles to gravitate into the hand or into any desired receptacle.

A suitable lock controlled removable closure 56 is provided for the bottom of the base A and this closure is provided with knobs 51.0f rubber or other material whereby the machine may be supported on polished surfaces without danger of marring such surfaces. The base A is provided with one or more inwardly directed lugs 58 (Fig.

3) whichunderlie and hold one side of the closure 58, while another lug. 59. which extends inwardly from the base overlies the closure 55 and constitutes a keeper above which the bolt 60 of the closure carried lock 6! is engageable to secure the closure in closing relation to the open bottom of the base. When the bolt 68 is retracted the closure is free to be removed from and applied to the base.

.As indicated at 62 in Fig. 2 of the drawings, the walll I is beveled toga. relatively thin edge at the forward end of. the slot 34 to avoid any possibility of crushing of articles between the wall defining the forward end of said slot and the rear wall of the well 38 when the disk-like element 35 is moved forwardly.

As illustrated in Figs. 2 and 4 of the drawings,

the top wall I I of the member B has a flange 33 extending upwardly therefrom at the outer side:

of theslot 34. When the machine is used for dispensing balls of candy, chewing gum or the like it is usual to provide for delivery of twosuch balls during each cycle of operation of the machine by proper adjustment of the member .58, and the purpose of the fiange63 is to prevent bridging by a third ball of two balls which drop into the well 38, thus to assure that only two balls will be delivered by the machine during each cycle of operation thereof. In this connection another feature of the invention resides in the provision of a pair of depressions 64 in the upper face of the wall ID as illustrated in Figs. 2 and 4 to receive and thus maintain properly spaced the two balls which gravitate into the well 34 during each cycle of operation of the machine. Because of the depressions 64 acting to hold the balls in predetermined spaced relationship, and acting in conjunction with the flange 63 to prevent wedging of a third ball into the well 38 there is obtained additionalinsurance against the delivery of more than two balls during any one cycle of operation of the machine. Obviously, by increasing the effective length of the well 38 and by providing an additional depression or depressions 64, the machine may readily be adapted for delivery of three or more balls during each cycle of operation thereof. Moreover, it is apparent that while the disks 35, 36 have been illustrated in the present instance as being rotatable in horizontal planes, it is within the purview of the invention to construct the machine so that these disks are rotatable in vertical planes.

From an inspection of the drawings the compactness and simplicity of the present machine,

the disposition of the spring 46 in an isolated position within the base A, the simple mounting of the disk-like elements 35 and 36 and various other features of advantage will be readily appreciated. Moreover, it is believed in view of the drawings and the foregoing description that the construction and operation of the machine Will be clearly understood. It is desired to point out, however, that while only a single specific embodiment of the machine has been illustrated and described, the same is readily capable of various modifications and that the different features thereof are readily capable of embodiment in machines of different design, within the spirit and scope of the invention as defined in the appended claims.
